A sealing member 95 is overmolded onto the connection port 81 around the entire circumference of the portion of the connection port 81 that extends into the connector opening 93 of the first housing part 19 . The sealing member 95 is in contact with the sealing surface 97 of the first housing part 19 over the entire circumference of the connector opening 93 . Sealing member 95 provides a seal that prevents liquid from entering between connection port 81 and first housing part 19 . The sealing member 95 is compressed between the first housing part 19 and the connection port 81 . The sealing member 95 is compressed between the first housing part 19 and the sealing surface 97 of the connection port 81 in a direction substantially perpendicular to the axial direction 20 .

FIG. 12 corresponds to FIG. 10 with the first housing part 19 removed. A spacer 99 is provided between the main body 65 of the aerosol generator 3 and the first housing part 19. Specifically, spacer 99 is provided between main body 65 and end surface 87 of first housing portion 19 . Two fixing elements 89 extend through the opening in spacer 99. The opening of the spacer 99 is coaxial with the mounting opening 91 of the first housing part 19.

FIG. 13 corresponds to FIG. 12 with spacer 99 removed. Between the main body 65 of the aerosol generator 3 and the spacer 99 there is an elastomer sealing layer 101. Fixation element 89 extends through the opening in elastomeric seal member 101 . The opening in elastomeric seal member 101 is coaxial with the opening in spacer 99 and with the mounting opening 91 in first housing portion 19 . When the fixing element 89 is tightened, the first housing part 19 is pressed against the outer surface of the spacer 99. As a result, spacer 99 forces elastomeric sealing layer 101 against body 65 , thereby compressing elastomeric sealing layer 101 between body 65 and first housing portion 19 . Elastomeric seal layer 101 can form a seal between body 65 and spacer 99. The seal may prevent liquid entering through the mounting opening 91 from flowing into the internal compartment of the aerosol generating device 3.

Spacer 99 may be formed from an elastomeric material. When the fixing element 89 is tightened, the spacer 99 is pressed against the first housing part 19, thereby establishing a seal between the first housing part 19 and the spacer 99, at least around the fixing element 89. be able to.

Spacer 99 and elastomeric seal member 101 may be integrally formed. For example, one of the spacer 99 and the elastomeric seal member 101 may be omitted and the other of the spacer 99 and the elastomeric seal member 101 may be compressed directly between the main body 65 and the first housing portion 19. good.
